Bioware’s space opera comes to a close next month with the release of the final part of Commander Sheppard’s odyssey, but if you need a hit of those sweet, sweet cosmic gaming juices before hand you can play the first mission from the game via the demo which is available on Xbox Live from today.

This previews is said to provide between an hour to two hours worth of gaming, which is not bad for a demo in our book and comes in at a very reasonable 1.76 gig worth of hard disc space. A sneak peak of the multiplayer side of the game can be accessed from the 17th of this month, but if you have redeemed the online pass for Battlefield 3 you can team up with other space-faring folks from today.

The full game arrives on Xbox 360, PS3 and PC, this coming March the 6th in the USA and the 9th in the EU.
